Breast Cancer

Among all cancers ladies, he takes the initial place. In most cases, breast cancer develops in the presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

Breast cancer is represented macroscopically nodular and diffuse forms, as well as cancer in the nipple along with the nipple in the field (Paget's disease in the breast). For the nodular cancers are seen as a the node using a diameter of up to several centimeters. In some instances, a decent knot, is permeated with whitish layers tissue penetrating in the surrounding fatty tissue, in others - a soft, juicy on the cut, splits easily. Diffuse prostate cancer is covered to get a considerable distance, the contours of the tumor are marked bad. Sometimes the cancer invades skin and forms around the surface of decaying mushroom formation - a cancerous ulcer. In some instances, the tumor spreads across the surface of the breast and all the iron is included having a dense shell.

In histological structure include the following forms of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancers might be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as an varying examples of tissue and cell irregularities, which able to distinguish different amount of malignancy. This type of cancer include, specifically, infiltrating ductal and lobular carcinoma, which in turn has the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The causes of breast cancers often are hormonal changes inside body: the entry into menopause, when there is an active restructuring in the hormonal regulation with the woman, the ovaries lose their activity, decreased production of progesterone and estrogen, one's body is going through, "hormonal crisis." The mammary gland and endometrium (lining from the uterus) are most attentive to these changes, the breast type tissue starts to dissolve and be replaced by fat.

Scientifically established the female hormones estrogen-, plays an integral role in the continuing development of cancer of the breast. The excess hormones inside body results in a favorable background for developing the disease. The least active hormones estrogen behave during pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (over 12 months) to reduce the chance of developing breast cancers. On the other hand, abortion cause hormonal "explosion" in a woman's body that will trigger the progression of tumors. So far there isn't any consensus concerning the impact about the development of tumors of hormonal contraceptive drugs, however it is thought that these drugs reduce potential risk of developing breast cancer, but increase potential risk of developing cancer of the female genital organs, and osteoporosis. In addition predisposition to breast cancers may cause harmful environmental factors: the planet, in addition to inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a family of first-degree relatives with breast cancers (mothers and sisters) likelihood of creating a tumor increasing by over half - familial forms of cancer.

Benign breast diseases including fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone usually do not cause cancer, but as well, create an unfavorable background for its development.

The cause of breast cancer could be the outcomes of radiation, like irradiation in the chest for other diseases (lung tumors, the lymphatic system), prolonged and frequent chest X-ray studies on inflammatory diseases or pulmonary tuberculosis.

Constitutional obesity can lead to cancer in the breast and female reproductive system, with an excess dimply skin inside the body, it might be a separate endocrine organ and begins to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are several forms of the growth of breast cancers:

- Nodular form, the most frequent, is characterized by a dense knot of 0.5 to five cm or even more, it is characterized by all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor with no clear boundaries, "spreading" in the breast and skin. For the first 2 forms are characteristic indications of inflammation: pain with the breast, a bright beautiful red colors of the skin it raises body's temperature to 39 degrees C. In view of those symptoms often occur, and errors in proper diagnosis of patients treated for inflammatory diseases, that happen to be named and are known as these forms breast cancers. When tubular carcinoma breast cancer cover as being a "skin" of its contracting and decreasing in space.

In certain cases, breast cancer manifests within the form of metastases within the lymph nodes about the affected side, often ceases to detect the tumor itself - show hidden cancer of the breast.

For small tumors of the breast, any symptoms arise. The most observant ladies and their husbands have the ability to detect tumor site in the gland unintentionally, but in a very large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks and only a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it's stationary or slightly shifted, may be firmly fixed to the surrounding tissue or skin, usually painless, can reach a significant size (more than 3 to 5 cm and often 10-15 cm).

Need to gauge the surface from the skin in the tumor: the malignant process will probably be observed retraction in the skin, picking up within the folds, wrinkles, a signal of "lemon peel" - a neighborhood swelling from the skin over the tumor, may be a direct tumor invasion to the skin surface, then it is a bright red color and sprawl as "cauliflower."
